FELIX LISAUSYO 2019 PRODUCTIONS
In case of chemicals with precautions, follow the precaution measures as
stipulated on the container of the chemicals.
Be conversant on how the apparatus can be operated and used.
The procedure or method
Clearly show the steps to be followed when conducting the investigation.
Indicate quantities which will be varied and vary at will.
Show how each quantity will be measured.
Indicate the value of the quantity that will be kept constant.
Repeated readings
This is done to improve the reliability of the results obtained.
Finding the average of the repeated results reduces experimental error.
THE STRUCTURE OF A SCIENTIFIC INVESTIGATION
Aim of the experiment
Is a belief and concise statement of the objective of the experiment.
Is derived from the hypothesis initially stated.
Apparatus/equipment to be used
Include all materials to be used.
These are identified and listed here.
Procedure/method
Is a section of step-by-step account of what is to be done.
You also indicate it will be done.
A well labelled diagram of the set-up should be included.
Quantities to be varied, measured, kept constant should be indicated clearly
with their values.
A statement on how the results will be analysed should be included.
Results
Results of measurements are shown here.
These include graphs, chart and tables.
Analysis
Is where the result of the investigation are discussed.
The usual points of discussion are
Trend of the graph
Explain why the graph curve decreases, increases or straight
line.
The gradient of the graph
Relate the quantities you are investigating with the gradient of
the graph where possible.
Area under the graph
It may sometimes be related to the quantity of investigation in
some way.
Conclusion
You state carefully the results analysed.
